URINAL.

Specification of Letters Patent.

Patented A11 2, 1910.

- Application filed September 28, 1909. Serial No. 519,976.

To all whom it may concern:

Be it known that I, NATHANIEL FROST, a citizen of the United States, anda resident of Bloomington, in the county of McLean and State ofIllinois, have invented a new and Improved Urinal, of which thefollowing is a full, clear, and exact description.

lhis invention relates to certain improvements in urinals, and moreparticularly to that type in which there is a substantially verticalback plate, to the upper edge of which water is delivered, and extendingoutwardly from which there are a plurality of partitions, divisions orscreens, to separate the device intoseparate or individual stalls. Theconstruction of these partitions or screens constitutes an importantfeature of my invention. In my improved device each partition issubstantially V-shaped in cross section and has its opposite edgesconnected to the spaced edges of separate back plates. Thus, the spacewithin the hollow partition is in free and open communication with thespace in the rear of the back plates, and the partition being hollow maybe formed of cast metal and may have its outer sides enameled. Thepartitions terminate at a considerable distance above the floor orwater-receiving trough, so that the latter may be readily cleaned, andeach of the back lates has substantially the upper half curve or bowedoutwardly to present a convex surface, while the lower portion issubstantially flat and is in the rear of the more advanced upperportion. The lower edge of the back plate is supported from the rearedge of the receiving trough but is s aced above the trough intermediatethe e dges of the latter; Thus, all water flowing down the front face ofthe back plate will be received directly in the trough, and air may bedrawn over the trough and through the space beneath the lower edge ofthe late to the ventilating chamber in the rear of the back plate. Thus,all odors arising from the trough are immediately carried away to theventilating chamber in the rear of the plate and to the outsideatmosphere, and the entire apparatus is kept in a sanitary condition.The water-delivering trough is spaced in the rear of the back plate andhas a forwardly and downwardly-curved lip extending over the plate sothat the trough is substantially concealed from view, yet delivers wateronly to the front face of the plate.

All of tlie features of my invention may be embodied in a singleconstruction and this may be made only of a length equivalent to asingle stall, or certain features may be omitted in the forming ofindividual stalls or ranges or batteries of them.

Reference is to be had to the accompanylng drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures, and in which Figure l is avertical transverse section through a device constructed in accordancewith my invention, presenting opposed rows of stalls; Fig. 2 is asection somewhat similar to Fig. 1, but showing the use of only a singlerow of stalls; Fig. 3 is a face view ofthe device shown in Fig. 1, thereceiving trough being shown in section; and Figs. 4 and 5 arehorizontal sections on the lines H and 5-5, respectively, of Fig. 3.

In the preferred form of my improved device, I employ a plurality orseries of back plates 10, over which water may flow from a deliverytrough 11 to a receiving trough 12. Each plate has the lower portion 13thereof substantially flat and preferably extending substantiallyvertical. The upper portion 14: of the plate is bowed or curvedforwardly so as to present a convex wall and to bring the u oper edge ofthe plate substantially in the p ane of the flat lower portion 13 and tobring the entire curved portion in advance or forward of the plateportion 13. The curved portion is of somewhat greater length than thelower flat portion, so that the plate substantially midway between theupper and the lower edges, extends rearwardly to intersect the flatportion at an obtuse angle. The plates have their adjacent edgesoverlapped to form seams 15 along the lower or flat portions, or theymay be secured together in any other suitable manner. The upper orcurved portions of the plates are spaced apart to leave elongatedopenings therebetween, and the opposed edges of the plates are providedwith rearwardly or inwardly-extending flanges 16. The plates support aplurality of partitions 17 each of which is substantially V-shaped incross section and is formed of metal with its outer surface enameled.Each partition has its front edge substantially straight and verticaland has its rear edge curved to conform to the curvature of the portion1 1 of the back plate. Along its rear edge, each partition has baseflanges 18, 18 for engagement with the front surface of the plates, andhas inwardly-extending flanges 19, 19 adapted to extend between theplates closely adjacent to the flanges 16, 16 of the latter and to bebolted or secured thereto in any suitable manner. The partitions do notextend down over the flat portion of the plates to any material extent,and thus terminate at a considerable distance above the lower orreceiving trough 12. The trough may thus be readily cleaned without anyobstruction or interference from the partitions. Each partition ishollow and its interior freely communicates with the space in the rearof the back plates. The bottom of each partition is closed by a portionintegral with the sides, while the top is preferably closed by a cap 20substantially triangular in form and having a rounded top and dependingflanges extending over the upper edges of the sides of its correspondingpartition.

At the lower edges of the back plates and adjacent the seams 15 are aplurality of rearwardly-extending brackets or feet 21, by means of whichthe plates are supported. The receiving trough 12 is provided withoutwardly-extending flanges 22 and 23 resting upon suitable foundations,and the brackets or feet 21 rest upon the rear flange 23 and space thelower edge of the plate over the trough and in advance of the rear edgeof the latter, so that all water flowing down the plate will bedelivered directly into the trough. Even in case water should leakthrough the plate to the rear surface thereof, it will still flow downthis surface and reach the trough. The front supporting flange 22 of thetrough is preferably covered by a tile or other flooring 24,, whichinclines downwardly and terminates over the trough and delivers directlythreinto. The space in the rear of the plates is provided with an outletconduit or ventilating duct 25, through which air is continuously drawnby a fan or by any suitable suctioncreating means. The air enters thespace in the rear of the plate by flowing directly across the trough andbeneath the under edge of the plate, so that all odors arising from thetrough will be carried directly into the rear of the plate rather thanascend into the room. Furthermore, the circulation of air in the spacein the rear of the plates keeps the rear surfaces of said platesthoroughly dry and in a sanitary condition, and prevents moisture fromcollecting should the water-delivering means leak or should the jointsbetween the plates become loosened.

For delivering water to the upper edge the upper portion of the plate.This curved edge is preferably provided with transverse corrugations orgrooves, so that the .water will be delivered evenly along the width ofthe plate. The lip may be spaced a very short distance from the top ofthe plate, so that a small amount of air may pass beneath the lip to theventilating chamber and keep the upper portion of the latter dry andsanitary. The troughs are so supported that they may be readily adjustedto a hori Zontal position, and a separate trough is preferably providedfor each individual plate. The troughs terminate adjacent the edges ofthe partitions and the plates extend upwardly above the troughs at eachend of the latter. Thus, the lip of the trough extends through atransverse opening or re cess in the upper edge of the plate. ater isdelivered to the troughs in any suitable manner, for instance, by adelivery conduit 28 parallel to the troughs and above the same andextending the full length of the device. The conduit may have one ormore delivery apertures for each individual trough. A cover plate 29 ispreferably mounted above the delivery conduit and serves to conceal thelatter and most of the trough from view. The plate is supported at itsrear edge and has its front edge curved downwardly and terminating inengagement with the front sides of the several plates 10 at the edges ofthe latter and adjacent the curved delivery lip 27 of the troughs butspaced from the latter, so as not to interfere with the free delivery ofthe water.

At the end of a range or battery of stalls, end plates 30 may beprovided, the shape of which will depend upon whether the series is toextend against a wall or within aroom. The plates may be ranged inparallel, so that a single ventilating space will draw water over twoseparate receiving troughs, as indicated in Fig. 1, or a single row ofplates may be provided and spaced a short distance from the wall of theroom, as indicated in Fig. 2. The water is kept at a predetermined levelin the receiving trough by any suitable form of trap or otherlevel-controlling means. In Fig. 3 I have illustrated a very simple formof trap including a small partition wall 31, over which the water mustflow to the screened outlet conduit 32.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:
